Specification forming part of Letters Patent No. 174,482, dated March 7,1876; application filed February '3, 1876.

. mon lever-cutter; and they consist in securing the cutter'lever to thefacing of the feedbox by means of a removable rotating conical bearing,as hereinafter specified.

The letter'a denotes the metallic facing of the feed-box; b, the knife;0, the lever hearing the knife, and also the horizontal leaf d, lying onand attached,-by bolts 0 e, to horizontal leaf f, which is fast on disk9., This 4 disk gis the frustum of a cone, and I-shall' herein refer toit as frusto-conical. It lies against the facing a, and, is held theretoby the two stationary fingers h h and the adjustable finger h. This diskforms the pivot for the vibrations of the lever 0.

In lever-cutters it is desirable that the knife should bear against thethroat of the facing a with increased pressure at the side of the throatfarthest removed from the pivot of the lever, and in use this pressureneeds to be increased by readjustment from time to time. In thismechanism I attain such adjustment by having the bolts 6 6 run throughslotst' i in the leaf f, which makes the two leaves d f adjustable oneupon the other.

I claim as my invention The combination of the frusto-conical disk 9,facing a, stationary fingers h h, and adjustable finge'r It, allsubstantially as described.
